Pre- and post-intervention survey on lung cancer awareness among adults in selected communities in KwaZulu-Natal, South Africa: A quasi-experimental study

Background: Lung cancer remains the number one cause of cancer mortality estimated at 1.8 million deaths. There are limited studies in resource poor countries regarding knowledge, attitudes and practices towards lung cancer. Objective: This study aimed to assess the effects of a lung can-cer awareness intervention in selected communities in KwaZulu-Natal, South Africa. Materials and Methods: A quasi-experimental study design was conducted in the selected communities in KwaZulu-Natal. A community intervention was administered in the communities after a baseline survey. The intervention effects were assessed a month after implementation. Results: There were statistical differences in the mean age (p<0.001) and proportion of males and females (p<0.001) at base-line and post-intervention. There were no differences in terms of smoking status (p=0.958), however, there was a reduction in the number of cigarettes smoked per day (p<0.001) and the number of packs smoked per week (p=0.026). The mean knowledge score increased from 41.8% (95% CI 35.7 – 47.9) at baseline to 59.9 (95% CI 53.8 – 66.0) post-intervention (p<0.001). The proportion of participants who were aware that lung cancer can be detected early increased from 46.5% (95% CI 39.1 – 53.9) at baseline to 81.1% (95% CI 71.7 – 87.9) post-intervention (p<0.001). The intervention had a statistically significant effect (aOR 4.370, 95%CI 1.477-12.928) on the level of lung cancer knowledge in the selected communities (p<0.001). Conclusions: Interventions increasing the recognition of signs and symptoms, focusing on the importance of early detection and health seeking behaviour (including screening), smoking cessa-tion, and addressing the perceived health system barriers are required

Distribution of cervical abnormalities detected by visual inspection with acetic acid in Swaziland, 2011-2014: A retrospective study.

BACKGROUND:  Cervical cancer is the fourth most common cancer worldwide among women, with the number of new cases increasing from 493 243 in 2002 to 527 000 in 2012. These numbers are likely to be underestimated because given the lack of registration resources, cervical cancer deaths are usually under-reported in low-income countries. AIM:  To describe the distribution of and trends in visual inspection with acetic acid (VIA) to detected cervical abnormalities in Swaziland by reviewing records of VIA examinations performed at two main hospitals in Swaziland between 2011 and 2014. SETTING:  Mbabane Government Hospital and Realign Fitkin Memorial (RFM). METHODS:  Records of cervical screening using VIA at the Mbabane government hospital and RFM hospital between 2011 and 2014 were retrieved. Positivity rates (PRs) of VIA with 95% confidence intervals (95% CI) were calculated and used as proxies of cervical abnormalities. Odds ratios of the association between VIA-detected cervical abnormalities and human immunodeficiency virus (HIV) status were estimated using logistic regressions. RESULTS:  VIA was positive in 1828 of 12 151 VIA records used for analysis (15%, 95% CI: 14.4-15.7). VIA was positive in 9% (36 of 403) women under the age of 20, in 15.5% (1714 of 11 046) of women aged 20-49 years and in 11.1% (78 of 624) of women aged 50-64 years. A decreasing trend of VIA positivity was observed over time at both screening centres (p for trend < 0.001). Of 2697 records with Papanicolaou results, 20% (67 of 331) VIA-positives and only 5% (114 of 2366) VIA negatives had high-grade squamous intraepithelial lesion. Among 4578 women with reported HIV status, 1702 were HIV-positive (37.2%, 95% CI: 35.8-38.6). The prevalence of HIV in VIA-positive women was 62.5% (95% CI: 58.7-66.2), almost double that among VIA-negative women (33.0%, 95% CI: 31.6-34.5) and that among all women screened (p < 0.001). HIV-positive women were 3.4 times more likely to have cervical abnormalities on VIA than HIV-negative women (OR: 3.4, 95% CI: 2.8-4.0, p < 0.01). CONCLUSION:  The high VIA PRs observed over four years in this study may reflect the prevalence of cervical abnormalities, in particular, in HIV-positive women. VIA is not a robust screening test, but it can play a major role in strengthening and expanding cervical cancer screening prevention programmes in resource-limited countries

The experiences of women diagnosed with uterine fibroids in the Kingdom of Eswatini

Background: Uterine fibroids (UFs) are benign uterine growths that significantly impact women’s daily activities, quality of life, fertility and expenditure. Aim: This study aimed to provide in-depth insights into the lived experiences of women diagnosed with UFs. Setting: The study was conducted in Eswatini health facilities across the four geographic regions. Methods: An explorative qualitative design was used; participants with confirmed UFs diagnoses or surgery related to UFs were purposively recruited for focus group discussions. Data collection was guided by the revised Wilson and Cleary model of health-related quality of life (HRQOL), which was iteratively analysed using Braun and Clark’s thematic analysis framework. Results: Sixty participants with confirmed UFs diagnoses or surgery related to UFs were included in this study. Five themes emerged: awareness of the disease, symptoms experienced, treatment and care, perceptions and beliefs and health-seeking behaviour. Most participants experienced physical symptoms, abdominal pain and vaginal bleeding. Among the emotional and psychological consequences experienced by the majority of participants were fear, worry, tension and (perceived) disrupted body image. The majority of the participants lacked knowledge of UFs, and their perceptions and health-seeking behaviour differed. Conclusion: Findings showed that most participants experienced physical, psychological, emotional and social challenges. Contribution: These experiences were influenced by lack of knowledge, symptoms experienced, poor treatment and care and perceptions and beliefs about UFs. Health education, client involvement, early diagnosis and effective treatment are recommended to improve the experiences of UFs

Cervical cancer management in Zimbabwe (2019–2020)

Background: Globally, cervical cancer is the fourth most commonly diagnosed cancer amongst women, and it is especially common in low- and middle-income countries (LMICs). The aim of the study was to determine the current patterns and characteristics of CC management in Zimbabwe in the HIV pandemic era, including the knowledge, attitude and practice of patience. Methods: The study was a mixed method which incorporated a cross-sectional survey of 408 CC patients which was conducted from October 2019 to September 2020 using an interviewer administered paper questionnaire. The study was conducted at Parirenyatwa hospital, the only cancer treating public health facility in Harare, Zimbabwe. Differences in study outcome by categorical variables were assessed using the Person Chi-square (χ2) test. Odds ratios (unadjusted and adjusted) and 95%CIs for potential risk factors associated with the outcome were estimated using logistic regression model. Results: From a total of 408 CC patients recruited into the study no prevention mechanism was available or known to these patients and only 13% knew that CC is caused by Human papillomavirus. Only 87 (21%) had ever been screened for CC and 83 (97%) of those who had been screened had the visual inspection with acetic acid procedure done. Prevention (screening uptake) is statistically high among the educated (with secondary education OR = 9.497, 95%CI: 2.349–38.390; with tertiary OR = 59.381, 95%CI: 11.937–295.380). Late presentation varied statistically significantly with marital status (high among the divorced, OR = 2.866; 95% CI: 1.549–5.305 and widowed OR = 1.997; 95% CI: 1.112–3.587), was low among the educated (Tertiary OR = .393; 95% CI: .166-.934), low among those living in the rural (OR = .613; 95% CI: .375-.987), high among those with higher parity OR = 1.294; 95% CI: 1.163–1.439). Less than 1% of the patients had surgery done as a means of treatment. Radiotherapy was administered to 350 (86%) of the patients compared to chemotherapy administered to 155 (38%). A total of 350 (86%) have failed to take medication due to its unavailability, while 344 (85%) missed taking medication due to unaffordability. Complementary and alternative medicines were utilized by 235 (58%). Majority, 278 (68%) were HIV positive, mainly pronounced within age (36–49 years OR = 12.673; 95% CI: 2.110–76.137), among those with higher education (secondary education OR = 4.981; 95%CI: 1.394–17.802 and in those with no co-morbidities (893.956; 95%CI: 129.611–6165.810). Conclusion: CC management was inadequate from prevention, screening, diagnosis, treatment and palliative care hence there is need to improve CC management in Zimbabwe if morbidity and mortality are to be reduced to acceptable levels. Education helped improve prevention, but reduces chances of diagnosis, working as a doubled edged sword in CC management Prevention was high among the educated. Those in rural areas experience poor CC management. It should be noted that general education is good; however it must be complimented by CC awareness to improve CC management outcomes holistically. Cervical cancer management services need to be decentralized so that those in rural areas have easy access. Given that those with co-morbidities and high parity have better CC management, CC services need to be tied to co-morbidity and antenatal/post-natal care and management services

Facilitating factors and barriers to accessibility and utilization of kangaroo mother care service among parents of low birth weight infants in Mangochi District, Malawi: a qualitative study

Kangaroo Mother Care (KMC) is one of the interventions widely used in low-income countries to manage Low Birth Weight Infants (LBWIs), a global leading cause of neonatal and child mortality. LBWI largely contributes to neonatal mortality in Malawi despite the country strengthening and implementing KMC, nationwide, to enhance the survival of LBWIs. This qualitative study aimed to assess the facilitating factors and barriers to accessibility and utilization of KMC service by the parent of low birth weight infants (PLBWIs) in Mangochi District, Malawi. Methods: Two focused group discussions assessed factors facilitating and hindering the accessibility and utilization of KMC service were conducted in April 2018 that reached out to (N = 12) participants; (n:6) PLBWI practicing KMC at Mangochi district hospital (MDH) referred from four health facilities and (n:6) high-risk pregnant mothers (HRPMs) visiting antenatal care (ANC) clinic at MDH. The availability of KMC at MDH was assessed using KMC availability checklist. The study used purposive, convenient and simple random sampling to identify eligible participants

Prevalence and risk factors associated with sexually transmitted infections (STIs) among women of reproductive age in Swaziland.

BACKGROUND: Sexually transmitted infections (STIs) remain an important public health problem with approximately half a billion new cases annually among persons aged 15-49 years. Epidemiological data on STIs among women of reproductive age in Swaziland are limited. The availability of epidemiological data on STIs and associated risk factors in this population is essential for the development of successful prevention, diagnosis and management strategies in the country. The study aimed to determine the prevalence and risk factors associated with STIs. METHODS: A total of 655 women aged 15-49 years were systematically enrolled from five health facilities using a cross-sectional study design. Cervical specimen were tested using GeneXpert CT/NG Assays for Chlamydia trachomatis (CT) and Neisseria gonorrhoeae (NG), GeneXpertTV Assay for Trichomonas vaginalis (TV), and GeneXpert HPV Assays for hr-HPV. Blood samples were tested using Alere Determine HIV-1/2Ag/Ab Combo and Trinity Biotech Uni-Gold Recombigen HIV test for confirmation for HIV, and Rapid Plasma Reagin and TPHA test for confirmation for Treponema pallidum (syphilis). Genital warts were assessed prior to specimen collection. Survey weighted analyses were done to estimate the population burden of STIs. RESULTS: The four most common curable STIs: CT, NG, TV, Treponema pallidum (syphilis), as well as genital warts were considered in this study. The overall weighted prevalence of any of these five STIs was 19.4% (95% CI: 14.9-24.8), corresponding to 72 990 women with STIs in Swaziland. The estimated prevalences were 7.0% (95% CI: 4.1-11.2) for CT, 6.0% (95% CI: 3.8-8.8) for NG, 8.4% (95% CI: 5.4-12.8) for TV, 1.4% (95% CI: 1.1-10.2) for syphilis and 2.0% (95% CI: 1.0-11.4) for genital warts. The overall weighted HIV prevalence was 42.7% (95%CI: 35.7-46.2). Among hr-HPV positive women, 18.8% (95% CI: 13.1-26.3) had one STI, while 6.3% (95% CI: 3.3-11.7) had multiple STIs. Risk factors associated with STIs were being employed (OR = 2.2, 95% CI: 1.0-4.7), self-employed (OR = 2.8, 95% CI: 1.5-5.5) and being hr-HPV positive (OR = 2.0, 95% CI: 1.3-3.1). Age (0.9, 95% CI: 0.8-0.9), being married (OR = 0.4, 95% CI: 0.3-0.7) and not using condoms with regular partners (OR = 0.5, 95% CI: 0.3-0.9) were inversely associated with STIs. CONCLUSION: STIs are highly prevalent among women of reproductive age in Swaziland. Thus, a comprehensive STIs screening, surveillance and treatment programme would be justified and could potentially lower the burden of STIs in the country

Prevalence of and Associated Risk Factors for High Risk Human Papillomavirus among Sexually Active Women, Swaziland.

BACKGROUND: High risk human papillomavirus (hr-HPV) infection and the dual burden of HIV remains a huge challenge in some low-income countries (LICs) such as Swaziland with limited or no data. We estimated the prevalence and investigated determinants of hr-HPV, including HIV infection among sexually active women in Swaziland. METHODS: A total of 655 women aged between 15 and 49 years from five health facilities were randomly enrolled using a cross-sectional study design. Cervical cells were tested for hr-HPV types using GeneXpert HPV Assays. RESULTS: The overall weighted hr-HPV prevalence was 46.2% (95%CI: 42.8-49.5). Of hr-HPV infected women, 12.4% (95%CI: 8.6-17.5) were HPV16-positive, 13.8% (95%CI:12.0-15.8) were positive for HPV18/45, 26.7% (95%CI: 24.2-29.3) for HPV31/33/35/52/58, 7.6% (95%CI: 7.6-11.9) for HPV51/59 and 11.0%, (95%CI: 7.9-15.3) for HPV39/56/66/68. Prevalence of hr-HPV decreased with increasing age. Overall HIV prevalence remained high (42.7%; 95%CI: 35.7-46.2). HIV infection was associated with hr-HPV infection (Adjusted OR = 4.9, 95%CI: 3.043-7.8, p<0.001). Overall hr-HPV/HIV co-infection was 24.4% (95%CI: 20.3-29.1) which was significantly higher among younger age groups (p<0.001). Prevalence of multiple group hr-HPV infection was significantly higher in HIV-positive versus -negative women (27.7% and 12.7% respectively, p<0.001). The presence, absence or unknown of history of STI with HIV did not appear to modify the relationship with hr-HPV (OR = 4.2, 95%CI: 2.6-7.1, OR = 4.6, 95%CI: 2.8-7.7, p<0.001, p<0.001 and OR = 4.1, 95%CI: 1.3-13.4, p<0.021 respectively). CONCLUSION: The prevalence of hr-HPV infection was high and significantly associated with HIV among sexually active women. Furthermore, the study has provided essential information about the HIV link with hr-HPV infections which may explain the high prevalence among HIV infected women. This can contribute to policy development and planning of prevention strategies incorporating HPV infection prevention especially among youth and HIV infected people

Health trends, inequalities and opportunities in South Africa's provinces, 1990-2019: findings from the Global Burden of Disease 2019 Study

Background Over the last 30 years, South Africa has experienced four ‘colliding epidemics’ of HIV and tuberculosis, chronic illness and mental health, injury and violence, and maternal, neonatal, and child mortality, which have had substantial effects on health and well-being. Using data from the 2019 Global Burden of Diseases, Injuries and Risk Factors Study (GBD 2019), we evaluated national and provincial health trends and progress towards important Sustainable Development Goal targets from 1990 to 2019. Methods We analysed GBD 2019 estimates of mortality, non-fatal health loss, summary health measures and risk factor burden, comparing trends over 1990–2007 and 2007–2019. Additionally, we decomposed changes in life expectancy by cause of death and assessed healthcare system performance. Results Across the nine provinces, inequalities in mortality and life expectancy increased over 1990–2007, largely due to differences in HIV/AIDS, then decreased over 2007–2019. Demographic change and increases in non-communicable diseases nearly doubled the number of years lived with disability between 1990 and 2019. From 1990 to 2019, risk factor burdens generally shifted from communicable and nutritional disease risks to non-communicable disease and injury risks; unsafe sex remained the top risk factor. Despite widespread improvements in healthcare system performance, the greatest gains were generally in economically advantaged provinces. Conclusions Reductions in HIV/AIDS and related conditions have led to improved health since 2007, though most provinces still lag in key areas. To achieve health targets, provincial governments should enhance health investments and exchange of knowledge, resources and best practices alongside populations that have been left behind, especially following the COVID-19 pandemic

Subnational mapping of HIV incidence and mortality among individuals aged 15–49 years in sub-Saharan Africa, 2000–18 : a modelling study

Background: High-resolution estimates of HIV burden across space and time provide an important tool for tracking and monitoring the progress of prevention and control efforts and assist with improving the precision and efficiency of targeting efforts. We aimed to assess HIV incidence and HIV mortality for all second-level administrative units across sub-Saharan Africa. Methods: In this modelling study, we developed a framework that used the geographically specific HIV prevalence data collected in seroprevalence surveys and antenatal care clinics to train a model that estimates HIV incidence and mortality among individuals aged 15–49 years. We used a model-based geostatistical framework to estimate HIV prevalence at the second administrative level in 44 countries in sub-Saharan Africa for 2000–18 and sought data on the number of individuals on antiretroviral therapy (ART) by second-level administrative unit. We then modified the Estimation and Projection Package (EPP) to use these HIV prevalence and treatment estimates to estimate HIV incidence and mortality by second-level administrative unit. Findings: The estimates suggest substantial variation in HIV incidence and mortality rates both between and within countries in sub-Saharan Africa, with 15 countries having a ten-times or greater difference in estimated HIV incidence between the second-level administrative units with the lowest and highest estimated incidence levels. Across all 44 countries in 2018, HIV incidence ranged from 2 ·8 (95% uncertainty interval 2·1–3·8) in Mauritania to 1585·9 (1369·4–1824·8) cases per 100 000 people in Lesotho and HIV mortality ranged from 0·8 (0·7–0·9) in Mauritania to 676· 5 (513· 6–888·0) deaths per 100 000 people in Lesotho. Variation in both incidence and mortality was substantially greater at the subnational level than at the national level and the highest estimated rates were accordingly higher. Among second-level administrative units, Guijá District, Gaza Province, Mozambique, had the highest estimated HIV incidence (4661·7 [2544·8–8120·3]) cases per 100000 people in 2018 and Inhassunge District, Zambezia Province, Mozambique, had the highest estimated HIV mortality rate (1163·0 [679·0–1866·8]) deaths per 100 000 people. Further, the rate of reduction in HIV incidence and mortality from 2000 to 2018, as well as the ratio of new infections to the number of people living with HIV was highly variable. Although most second-level administrative units had declines in the number of new cases (3316 [81· 1%] of 4087 units) and number of deaths (3325 [81·4%]), nearly all appeared well short of the targeted 75% reduction in new cases and deaths between 2010 and 2020. Interpretation: Our estimates suggest that most second-level administrative units in sub-Saharan Africa are falling short of the targeted 75% reduction in new cases and deaths by 2020, which is further compounded by substantial within-country variability. These estimates will help decision makers and programme implementers expand access to ART and better target health resources to higher burden subnational areas

Mapping geographical inequalities in access to drinking water and sanitation facilities in low-income and middle-income countries, 2000-17

Background: Universal access to safe drinking water and sanitation facilities is an essential human right, recognised in the Sustainable Development Goals as crucial for preventing disease and improving human wellbeing. Comprehensive, high-resolution estimates are important to inform progress towards achieving this goal. We aimed to produce high-resolution geospatial estimates of access to drinking water and sanitation facilities. Methods: We used a Bayesian geostatistical model and data from 600 sources across more than 88 low-income and middle-income countries (LMICs) to estimate access to drinking water and sanitation facilities on continuous continent-wide surfaces from 2000 to 2017, and aggregated results to policy-relevant administrative units. We estimated mutually exclusive and collectively exhaustive subcategories of facilities for drinking water (piped water on or off premises, other improved facilities, unimproved, and surface water) and sanitation facilities (septic or sewer sanitation, other improved, unimproved, and open defecation) with use of ordinal regression. We also estimated the number of diarrhoeal deaths in children younger than 5 years attributed to unsafe facilities and estimated deaths that were averted by increased access to safe facilities in 2017, and analysed geographical inequality in access within LMICs. Findings: Across LMICs, access to both piped water and improved water overall increased between 2000 and 2017, with progress varying spatially. For piped water, the safest water facility type, access increased from 40·0% (95% uncertainty interval [UI] 39·4–40·7) to 50·3% (50·0–50·5), but was lowest in sub-Saharan Africa, where access to piped water was mostly concentrated in urban centres. Access to both sewer or septic sanitation and improved sanitation overall also increased across all LMICs during the study period. For sewer or septic sanitation, access was 46·3% (95% UI 46·1–46·5) in 2017, compared with 28·7% (28·5–29·0) in 2000. Although some units improved access to the safest drinking water or sanitation facilities since 2000, a large absolute number of people continued to not have access in several units with high access to such facilities (>80%) in 2017. More than 253 000 people did not have access to sewer or septic sanitation facilities in the city of Harare, Zimbabwe, despite 88·6% (95% UI 87·2–89·7) access overall. Many units were able to transition from the least safe facilities in 2000 to safe facilities by 2017; for units in which populations primarily practised open defecation in 2000, 686 (95% UI 664–711) of the 1830 (1797–1863) units transitioned to the use of improved sanitation. Geographical disparities in access to improved water across units decreased in 76·1% (95% UI 71·6–80·7) of countries from 2000 to 2017, and in 53·9% (50·6–59·6) of countries for access to improved sanitation, but remained evident subnationally in most countries in 2017. Interpretation: Our estimates, combined with geospatial trends in diarrhoeal burden, identify where efforts to increase access to safe drinking water and sanitation facilities are most needed. By highlighting areas with successful approaches or in need of targeted interventions, our estimates can enable precision public health to effectively progress towards universal access to safe water and sanitation
